Body

The Environmental Sustainability major brings together the natural sciences, social sciences, and cutting-edge data tools to help students understand how the Earth works—and how we can care for it. Students explore everything from biodiversity, ecology, and climate processes to the forces that shape landscapes, oceans, and weather. Whether you’re studying the emergence of life, tracking severe storms, or examining how rivers, hazards, and resources evolve, you’ll gain a deep foundation in the interconnected systems that sustain our planet.

Beyond the physical sciences, the major also examines how people, places, and policies influence environmental outcomes. Courses in environmental economics, global food systems, sustainability planning, environmental writing, and the human dimensions of climate change give students the tools to create meaningful change in communities and organizations. With advanced options in GIS, remote sensing, restoration ecology, energy systems, and more, the major empowers students to tailor their path and prepare for careers across science, policy, communication, and sustainability practice.

Outline of the ES Bachelor of Science in Liberal Arts and Sciences

Body

The ES program offers a unique combination of structure and flexibility not found in most programs at the University of Illinois. Since most students are not accustomed to the level of choice we offer in our majors, the ES program has professors ready to advise you on tailoring your degree.

One Concentration (18-22 hours)

  • Society and Environment (SAE) OR
  • Science of the Earth System (SES)

ES Introductory Core: Required Courses (10 hours)

  • ESE 200: Earth's Physical Systems
  • ENSU 300: Environmental Sustainability
  • ESE 379: Intro to GIS Systems

ES Advanced Courses (18-24 hours)

  • Six advanced courses from the approved list, four must be from the ESE or ENSU rubric.

Choose a Concentration

After studying cross-disciplinary introductory classes, ESES students choose to focus in one of two concentrations, depending on their developing interests.

Title
SAE: Society and Environment, 18 - 21 Hours
Body

Substitutions may be made with advisor approval.

The SAE concentration offers a balanced cross-disciplinary social science/humanities education, emphasizing the political, socio-cultural, economic, and historical dimensions of sustainability. Students in this track might be interested in focusing on these areas:

  • Environmental Policy
  • Environmental Economics
  • Studies in Science and Technology
  • Social Valuation of Environmental Systems
  • Social Studies of the Physical Environment
  • Environmental History
  • Social Movements and the Environment
  • Perceptions of Environmental Risk
  • Environmental Ethics
Title
SES: Science of the Earth System, 20-22 Hours
Body

Substitutions may be made with advisor approval.

The SES concentration is a rigorous scientific program in the geophysical and ecological sciences focused on the complexity and interactions of natural systems. Students in this track might be interested in focusing on these areas:

  • Water/Hydrology
  • Ecology and Ecosystems
  • Data and Modeling
  • Engineering and Management Practices
  • Climate and Global Change
  • Biogeochemical Cycles
  • Types of Pollution and Their Sources
  • Remote Sensing
  • Sustainability Applications of GIS
  • Green Chemistry

ES Courses by level

Learn more about the courses that make up the ES course levels.

ES Required Core, 10 Hours

Both of the courses below are required. ESE 200 is a general introduction to sustainability and is followed by the intermediate course ENSU 300. ESE/GGIS 379 introduces students to the software and practices for viewing data on a map in ArcGIS. Typically, ESE 200 is offered in the Fall semester, ENSU 300 is offered in the Spring semester, while ESE/GGIS 379 is available in both the Fall and Spring semesters.

ES Advanced Courses, 18-24 Hours

A minimum of six (6) 300- and 400-level courses, from the approved list, are required. At least three of these five advanced courses must be listed or cross-listed as an ESE or ENSU course. Advanced courses will, in most circumstances, count toward the LAS requirement of 21 hours of 300- or 400-level courses overall, and 12 hours of 300- or 400-level courses in the major. It is strongly recommended that students complete the LAS requirement with 21 hours of 300- or 400-level courses related to the ESE curriculum. Please note that your DARS report will not show these requirements as being met until you complete a Major Plan of Study with your advisor.

Looking for hands-on experience in a class? Consider ESE 401: ESE Capstone. ESE 401 provides a pathway for students to earn course credit for a senior thesis or an internship experience. Make an appointment with Dr. Jonathan Tomkin to learn more about ESE 401.
